Abstract
The utility model relates to a light-emitting diode (LED) automobile headlamp module which comprises a concentrated reflection cup, a sealing groove and an optical diffusion sheet. The sealing groove is formed at the front end of the concentrated reflection cup, and the optical diffusion sheet is arranged inside the sealing groove. On one hand, after light of the LED automobile headlamp module passes through the concentrated reflection cup and is converged, the light is spread by the optical diffusion sheet in a horizontal mode to be used for illuminating as a dipped headlight, on the other hand, after the light of the LED lamp passes through the concentrated reflection cup and is converged, high beam illumination of the LED lamp is achieved through combination of liquid filling and the optical diffusion sheet. The LED automobile headlamp module is simple in structure, and good in light utilization rate of a light-emitting unit. Due to the fact that the liquid is filled between the sealing groove and a storage groove, switching of a high beam light and a dipped headlight is achieved, and the LED automobile headlamp module is convenient to use and operate, and capable of controlling an integrated structure to be in a small size, and revealing advantages of microminiaturization of the LED lamp. An added driving device is capable of automatically achieving switching of the high beam light and the dipped headlight, and operation is convenient.
Description
Technical field
The utility model relates to a kind of LED headlamp module, relates in particular to a kind of LED car headlamp module.
Background technology
Compare with common bulb, remarkable advantage such as that light emitting diode has is more energy-conservation, vibration resistance strike, long service life, volume are little, therefore LED more is applicable to automotive lighting and indication, and LED promotes the use of in multiple car light, as instrument panel lamp, brake lamp, steering indicating light etc.
At present, it is light source that car headlamp mainly adopts Halogen lamp LED, and the mode by the optically focused reflector reflects light in vehicle front.Because the light efficiency of halogen light source is low than LED, caloric value is big, the life-span is short, so a little less than the existing car headlamp ubiquity energy consumption height, illumination, caloric value is big, the life-span lacks problem, have certain potential safety hazard.
The structure of existing car headlamp is quite complicated, though existing many moneys automobile adopts LED as headlamp light source, but, complicated Vehicle lamp structure makes the LED headlamp have that the luminescence unit light utilization efficiency is not high, heat radiation is bad, light decay serious, can't form defectives such as desirable distance light hot spot and dipped beam spot, makes the advantage of light source microminiaturization of LED headlamp to bring into play.
On the other hand, existing various car headlamps, high beam and dipped headlights mostly are module separately in the design, use inconvenient.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of LED car headlamp module is provided.
The technical scheme that realizes the utility model purpose is: LED car headlamp module, comprise optically focused reflector, seal groove and optical diffusion sheet, and the front end of described optically focused reflector is provided with described seal groove, and described optical diffusion sheet is arranged in the described seal groove.
Preferably, also be provided with filling liquid in the described seal groove.
Preferably, described filling liquid is transparent filling liquid, and the refractive index of described filling liquid is identical with the refractive index of described optical diffusion sheet.
Preferably, described optical diffusion sheet is fixed in the described seal groove by glue.
Preferably, described optical diffusion sheet is fixed in the described seal groove by screw.
Preferably, described seal groove is cylindrical shape or cubic.
Preferably, also comprise accumulator tank, described accumulator tank is connected with described seal groove by pipeline.
Preferably, also comprise drive unit, described drive unit is connected with described seal groove or described accumulator tank.
Preferably, described drive unit is motor or group Pu.
The utlity model has positive effect: after the light of (1) LED lamp was assembled through the optically focused reflector, horizontal proliferation is the dipped headlights illumination through optical diffusion sheet, and was simple in structure, luminescence unit light utilization efficiency height;
(2) after the light of LED lamp is assembled through the optically focused reflector, through the high beam illumination that the LED lamp is realized in the back that combines of filling liquid with optical diffusion sheet;
(3) accumulator tank of Zeng Jiaing can be filled filling liquid or discharge in the accumulator tank from seal groove, thereby realizes the switching between high beam, the dipped headlights, use easy to operate, the structural design advantages of simple;
(4) drive unit of Zeng Jiaing can be realized the switching between high beam, the dipped headlights automatically, and is easy to operate.
